A self cooling can has water on a pre-wetted wick (478), in a chamber and an adsorbent in another chamber communicable upon actuation of the can with the chamber. One or both of the chambers is at low pressure. Upon actuation the pressure of the wick drops, water vapour is absorbed by the adsorbent from the internal atmosphere and more water evaporates from the wick to replace it, thereby causing a cooling effect in heat generated in the adsorbent may be contained by but a take-up system, such as phase change material or microcapsules of high heat capacity material such as water.

1. A self-cooling beverage container having a beverage chamber adapted to hold a beverage, an adsorbent, an evaporative refrigerant, an isolator isolating the refrigerant from the adsorbent, and an actuator adapted in use to communicate the adsorbent with the refrigerant so that, in use, the evaporative refrigerant evaporates and is adsorbed by the adsorbent, evaporation causing cooling of the beverage in use, wherein there is provided a beverage mixing means adapted to ensure that the beverage to be cooled is mixed or made turbulent during cooling of the beverage.
